Abstract: The present invention generally relates to a folding step stool that is, in one embodiment, mounted and stored within a cabinet. Children and short adults are typically not tall enough to readily access a kitchen or bathroom sink. Accordingly, many homes have a portable step stool located in the kitchen or bathroom. While effective, one problem with such a portable step stool is storage of the stool when not in use. Aspects of the present invention are directed to a folding step stool that may be mounted within an interior of a cabinet. When not in use, the entirety of the folding step stool may be disposed within an interior of the cabinet to permit closure of the cabinet door. Likewise, when needed, the cabinet door may be opened and the step stool may be deployed to provide one or more steps for use in accessing a counter or sink above the cabinet.

A cam surface on one of the uprights, when the uprights are going toward nested position, bears against a notched lever mechanism including a cap pivoted on the other one of said uprights. Normally, the lever mechanism is urged by a spring into latching position. The movement of the movable upright with respect to the other upright cams the cap and lever out of the way. The first and second uprights, when nested, are in a position with a flange on one of the uprights in a notch in the lever so that the uprights are contained in nested position. There is a pull cord for releasing the lever mechanism.
